NASA is offering up wreckage from the Challenger and Columbia for public view after hiding it from the world for decades. It is an unprecedented collection of artifacts — the first time, in fact, that any Challenger or Columbia remains have been openly displayed. NASA's intent is to show how the astronauts lived, rather than how they died.

This is an astronomy story that comes up only once in a blue moon, like on Friday. When the full moon appears at 6:43 a.m. EDT (1043 GMT) in the U.S. Friday, it will become the second full moon of July. Geoff Chester of the U.S. Naval Observatory said the traditional definition of a blue moon is two full moons in a m …

"Most of the known planets are hundreds of light-years away. This one is practically a next-door neighbour," said Lars A. Buchhave, an astronomer at the Harvard-Smithsonian Center for Astrophysics, in a statement today. Buchhave is the co-author of a paper about the planet accepted for publication in the journal Astronomy …

NASA’a Kepler planet-hunting mission has discovered an ‘Earth-like’ planet orbiting around a distant star. Located 1,400 light-years away, in the Cygnus constellation, Kepler-452b is the first Earth-sized planet to be found in the ’habitable zone’ - the area around a star such as the sun, where water remains as a liquid, …

NASA has announced the discovery of a new planet outside our solar system that it describes as the "closest twin" to Earth found to date. Kepler 452b, discovered using the planet-hunting Kepler Space Telescope, is about 60 per cent larger than Earth, making it a type of planet called a super-Earth, but scientists think it …

NASA has released more images of Pluto after the spacecraft New Horizons made its historic flyby of the dwarf planet earlier in the week. One photo shows a carbon monoxide-rich area within the Tombaugh region, Pluto's vast heart-shaped feature. "There is no other carbon monoxide concentration [on Pluto] like this," said …

Claudia Alexander, a brilliant, pioneering scientist who helped direct both NASA's Galileo mission to Jupiter and the international Rosetta space-exploration project, has died at age 56. Pasadena's Jet Propulsion Laboratory, where Alexander worked as the U.S. leader on the Rosetta Project, announced her death Thursday. …

A piece of space junk forced the three space station astronauts to seek emergency shelter Thursday. For nearly an hour, the American and two Russians hunkered down in their Soyuz capsule, which is docked to the International Space Station, in case they had to make a quick getaway. "Happy there was no impact," NASA astronaut …

The first close-ups of Pluto and Charon from the New Horizons spacecraft's historic flyby yesterday have revealed some surprises, NASA scientists said today. New images of Pluto and its moons Charon and Hydra were unveiled at a news conference Wednesday afternoon. A detailed image of Pluto's largest moon Charon showed …

Since being discovered in 1930, Pluto has been a deep mystery to the space community. On Tuesday, however, scientists will get their closest and clearest look at the dwarf planet when NASA's New Horizons spacecraft is expected to get within 12,500 kilometres of its surface. The unmanned spacecraft, the size of a piano, …

Blais posted the video on YouTube on Sunday. Like his previous musical astronomy videos, it's a video mosaic showing him performing all of the song's tracks — the vocals, beat-boxing and every bit of the big brass sound from the original song.

The team guiding the New Horizons spacecraft has been able to "nail its position very precisely," guaranteeing the probe will capture a flood of data about Pluto during Tuesday's flyby, a NASA scientist says. The spacecraft is on track to enter a tiny "box" that measures just 96-by-144 kilometres (60-by-90 miles) and New …

On Tuesday, NASA's aptly named New Horizons spacecraft will reach its closest distance from Pluto with a 30-minute flyby of the difficult-to-see dwarf planet. At its closest, about 12,500 kilometres away from Pluto, New Horizons is expected to produce never before seen clear, colour images of the icy object, and should reveal …

On July 14, NASA's aptly-named New Horizons spacecraft will reach its closest distance from Pluto with a 30-minute flyby of the difficult-to-see dwarf planet, which is the among the furthest known bodies from the sun. At its closest, about 12,500 kilometres away from Pluto, New Horizons is expected to produce never before …

Pluto, reveal thyself, and Earthlings, enjoy the show. On Tuesday, NASA's New Horizons spacecraft will sweep past Pluto and present the previously unexplored world in all its icy glory. The curtain hasn't been pulled back like this since NASA's Voyager 2 shed light on Neptune in 1989.
